Simos couldn't have been more helpful & flexible with how long we wanted use of the quad bike, which turned out to be the whole duration of our holiday on Santorini. The bike was in immaculate condition & perfect for the terrain we covered! Simos enhanced our island experience with his knowledge of the best restaurants, beaches, coves, villages etc. It's really worth asking him about the history of the island too as it's fascinating & he clearly knows his stuff! Thanks very much to you Simos & your team.
